Analysts say the online sales are growing as shoppers become comfortable with, if not hooked on the convenience of the Web and the deals to be found. Adding to the boom are sales from smartphones and tablet computers.

The National Retail Federation coined the term "Cyber Monday" in 2005 as data showed people were doing a lot of shopping on their work computers on the Monday following Thanksgiving. But it now looks like the advances in technology could allow companies to reclaim some of that lost productivity. The group's digital division Shop.org says people are relying less on work computers to shop with the growth in high speed Internet access and the popularity of mobile devices.
